Artificial intelligence firms have aggressively expanded their office presence in New York City and San Francisco since 2023. These companies are leasing millions of square feet to accommodate projected headcount growth and access specialized industry talent.
Why it matters
Operators face a changing real estate landscape as AI firms move to secure hubs in major finance and media markets. The expansion signals a commitment to in-person operations, with 50 to 60 percent of the new space specifically allocated for staff not yet hired.
AI companies accounted for 30 percent of leasing activity in San Francisco since 2023. Recent deals include Anthropic's 1.1 million square feet of total new space, with starting rents at 300 Howard Street reaching $87 per square foot.
The players
Anthropic
An AI research and development company that has scaled its office footprint by 1.1 million square feet.
OpenAI
A leading AI developer that leased 282,000 square feet in the San Francisco Bay Area.
Databricks
A data and AI enterprise software firm that leased 180,000 square feet at 100 Altair Way.
Ramp
A corporate card and spend management platform that added 285,000 square feet to its New York office.
Sierra AI
An artificial intelligence developer that leased 258,000 square feet at 185 Berry Street.
The details
Companies are locking in large-scale office footprints across multiple markets to recruit specialized skill sets. Firms like Anthropic, OpenAI, and Databricks are paying premium rents to locate near key industry clusters. The strategy involves securing space for future expansion, with more than half of the square footage intended for employees not yet on the payroll.
Timeline
2023 marked the start of industry data tracking for AI-specific office leasing.
Anthropic signed the lease for 300 Howard Street in February 2026.
Anthropic secured the space at 330 Hudson Street in July 2026.
Market Landscape
This wave of expansion marks a significant acceleration from the 2023 leasing trends identified by CBRE. The shift follows a decade of evolving hiring preferences for computer science graduates that began around 2015.
Operators should monitor local commercial rent trends in tech hubs as premium demand from AI firms creates upward pressure on pricing. Managers should also evaluate whether their current talent acquisition strategy remains competitive against firms prioritizing centralized, large-scale office environments.
The takeaway
The trend confirms that high-growth AI firms are prioritizing physical presence as a tool for talent recruitment. Operators should benchmark their own office occupancy policies against these industry heavyweights to determine if a shift back to centralized hubs could improve their own competitive hiring position.
